That image does not show a constant shuffle ratio. So the way I have done shuffle with the A-155 using the A-162 may not work, but it DOES work for a single set ratio. As there are two delays on the A-162, it may be possible to have two different ratios to choose from. Let me think for a second, and I apologize if these methods have been already suggested.

First, if you can find a drum machine with trigger outs and shuffle (like a TR-707 or a Machinedrum), send the trig out to the A-155 Clock In. This is the easiest way, and you can have any rhythm of pattern without concerns of clock division, delays, switches, etc. Preferably it is a drum machine with a good song sequencer and other MIDI, DinSync, or clock interface options. The programmed trigger pattern advances the A-155 clock/step-position. One of the A-155 Trig or Gate outputs triggers the relevant VCA envelope. Rests in the pattern are inserted by using the trigger and gate switches, turning that step off for the output you are using.
I take it back, the easiest way is to have a MIDI/CV converter send a gate pattern from a DAW sequencer, and you set the pitches and step on/off for each step at the A-155.


For more modular-based, constant 16th note patterns these methods work great, but if you intend to have rests in your pattern it gets a bit more tricky.


If I want a constant 16th note pattern with one shuffle ratio (I now realize two ratios are possible):

Take an 1/8th note clock signal derived from the master clock, using either an LFO, a MIDI/CV device, another step sequencer (I use a row on one of my MAQs with an eighth note gate pattern), etc. This signal is split and sent to the input of an A-162 TDEL and a trigger combiner module of some sort, either a DIY module with a few diodes, a Logic module, or a Trigger Combiner module like one that Doepfer now offers. The A-162 TDEL output goes to the other input of the combiner. The Combiner output goes to A-155 Clock in. One of the A-155 Trig or Gate outputs triggers the relevant VCA envelope.
As the eighth note clock pattern is creating the shuffled note from the quantized note, any rest in the clock pattern eliminates the shuffled note after the rest. Instead, rests in the pattern are inserted by using the trigger and gate switches, turning that step off for the output you are using. Because the clock step creates the shuffled note with an A-162 and there is so much space between clock steps, you can tune in shuffled values below 50%! What else can do this At a value of 50% (tuned by using the A-162 Delay control), you would have a normal 16th note pattern. Less delay = shuffle below 50%, more delay = shuffle over 50%.
Furthermore, you could insert a switch of some kind, either a manual toggle or an A-150 VC Switch. With this switch, you can turn the shuffle off and on without dialing the change manually. Either use the other half of the A-162 to create a 50% shuffle, and switch between them between the A-162 out and the trigger combiner. Or, if you derived your eighth note clock from a faster clock and a divider, use the 16th note out from the divider and switch between the steady 16th clock and the trigger combiner output going to the A-155 Clock in.
I suppose you could switch between delayed variations by deriving your 1/8th clock from a 16th note clock source and a clock divider. The /2 out would provide your 1/8th clock. The /4 out would provide a 1/4 note pulse which you could use to switch an A-150 between the two delay variations before the trigger combiner. I haven't tried this but it seems like it would work. Maybe you could also use an A-115 Audio Divider. Either way, there could be some undesired overlap if delayed notes are pushed or pulled to far, because the A-162 output is set with the Length control, and always plays the full length once triggered.


Another way I tried was with with an A-151 Quad Seq Switch:

Use a 16th note clock signal. Split the clock signal and send to A-151 Trig In, I/O1, and I/O3. Send a delayed version of this signal to I/O2 and I/O4. Send the Master I/O signal to the A-155 clock in. Trigger/Gate row to ADSR. Each clock pulse switches between quantized trigger and shuffled trigger. Two different shuffle ratios can be sent to I/O2 and I/O4, but they will only be >50% because the delayed note is triggered by the 16th note clock, unlike the 8th note clock in the previous example. Rests are inserted as in the previous examples. Rests in the clock pattern would result in the shuffled triggers occurring where the quantized triggers should.


Any thoughts on these methods
